Carburetion of a lean air-fuel mixture is proposed for reduction of all major contaminants emitted from automotive exhaust. Since the mixture lean limits tolerable by an internal combustion engine equipped with conventional carburetor make this approach unsuitable for nitrogen oxides control, exhaust gas recirculation as a supplemental control method is considered.Good fuel atomization and homogeneous mixing with air prior to admission into the inlet manifold eliminate “power surging” and extend the mixture lean limit of satisfactory engine operation. These tasks can be accomplished by pneumatic fuel atomization carburetion. Experimental results indicate effective reduction of unburned hydrocarbons, carbon monoxide, and nitrogen oxides as well as good engine performance at air-fuel ratio settings over 18:1.
